Gmail becomes the fourth Android app to reach 10 billion instals.

The Gmail app for Android has surpassed 10 billion instals, making it the fourth most popular software on the platform. Google Play Services, YouTube, and Google Maps are the three Google Play Store apps that have surpassed the one billion install mark. Since its inception in April 2004, Google's email service has been a popular choice among users. Gmail has lately received a lot of enhancements from Google. The most recent is an enhancement to Gmail's Undo feature, which allows users to go back in time and recall emails. 

Android police were the first to notice Gmail's admission into the billion-download club. It also explains how Google Maps and YouTube followed suit after Google Play Services hit the 10-billion-install mark. Gmail is the fourth most popular email service.

Gmail now includes a lot of useful features. Google's mail service just included the ability to undo a sent email in a number of time frames — 5 seconds, 10 seconds, 20 seconds, or 30 seconds. Previously, Gmail offered a five-second buffer for retrieving accidentally sent messages. Undo functionality for Gmail messages is accessible on the web and in the Gmail mobile apps. 

Google Chat has received yet another update from Gmail. Users will also be able to make one-on-one audio and video calls. The corporation has made this upgrade available to Android and iOS users in particular. Individual users on the chat list are the only ones who can make these calls. From the conversation, users can also check missed calls and current call data.
